Conspiracy theorists never get a "you were right" moment. Because usually once they are proven right, it's like a switch gets flipped in everyone and suddenly they simply don't care.
That's what movies and entertainment doesn't get right. Once the conspiracy is uncovered suddenly everyone gets up in Arms and demands justice and there's some kind of resolution.
But the 90s RPG Arcanum: Of Steamworks and Magic Obscura, has one of the most accurate and chilling depictions of a conspiracy in modern entertainment.
Spoilers for a side quest in a decades old game ahead
But there's a side quest where you the player get tipped off to some shady business going on at an island facility. When you get there, you come across a grisly scene. Blood, some bodies and horror show rooms. With plenty of full and half Ogres along with some gnomes.
The gnomes, it turns out, have been running an operation. Kidnapping women from around the country and taking them to the island to be forcibly impregnated by ogres to breed subservient half ogre children. Often times dying in the process after a couple births. It's tragic, dark and horribly fucked up. This is usually when it clicks in the players head that every gnome they run into, seems to be flanked by half ogre bodyguards. This side quest explains that's all half ogres are made this way, which adds an extra layer of tragedy to the player character of they choose to be a half ogre at the start.
The gnomes conspiracy is so wide reaching, that they kidnapped the royal family of the kingdom, and did this to the queen until she died, because the royal family displeased them.
After discovering this awful revelation, you can return to the mainland and expose it all to a local newspaper. The journalist is horrified over it and vows that the people must know.
Wait a few days, and returning to that same paper you'll find the journalist is gone, replaced with a gnome. Who claims to have no idea what you're talking about, and has never heard of that journalist ever working there. If you return to the island, the entire operation is gone. Everything has been cleaned up. With no trace of the operation left behind or proof that it happened.
that is how the quest ends. You didn't stop it, you don't affect it in any meaningful way, you don't even have proof at the end. There is no resolution, you just found something nobody was supposed to know about and they cover it up and the game moves on.
It is to this day, the most accurate depiction of a conspiracy and cover up that I know about in a video game or entertainment medium.
